Cu (I)-Catalyzed Synthesis of Polysubstituted Pyrroles from Dialkyl Ethylenedicarboxylates and β-Enamino Ketones or Esters in the Presence of O₂

Abstract

A straightforward method for the synthesis of polysubstituted pyrroles was achieved easily from oxidative cyclization of beta-enamino ketones or esters and alkynoates catalyzed by CuI in the presence of O(2).
